Relation of yields of soybean and maize to sulphur, zinc and copper status of soils under intensifying cropping systems in the tropical savannas of northeast Nigeria
Deficiencies of sulphur (S), copper (Cu) and zinc (Zn) are becoming prevalent under intensifying agricultural systems in north-eastern Nigeria. They are manifest in the partial or lack of response by crops to NPK fertilizers leading to a reduction in crop quality and yields. Data were collected on t...
